ROTATING-CYLINDER ENGINE.

SPECIFICATION forming part of Letters Patent No. 492,859, dated March '7, 1893.

Application filed July 30, 1891. Serial No. 401,208- (No model.)

To aZZ whom it may concern.-

Be it known that I, SAMUEL GLENVILLE BROSIUS, a citizen of the United States, residing at Savannah, in the county of Ohatham and State of Georgia, have invented certain new and useful Improvements in Rotating- CylinderEngines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable oth ers skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in rotating cylinder engines, of the class as shown in United States Patents Nos. 453,612, 453,613, 453,614, and 453,615, granted to me, and has for its objects to make a simple and an economically constructed and operative rotating cylinder engine.

In the drawings which illustrate my inventionFigure 1 is a side elevation, the cylinder, pistons and abutment disks and links being shown in cross section. Fig. 2 is an end view on lines l2 of Fig. 1, looking in the direction of the arrow. Figs. 3 and 4 are detail views of the piston crank, Fig. at being a cross section on lines 3-4 of Fig. 3. Figs. 5 and 6 are respectively end and side elevations ofthe link. Figs. 7 and'8 are respectively end and side elevations of the cam. Fig. 9 is a front elevation of the engine, the cylinder and one piston being shown partly in cross section. Figs. 10, 11 and 12 are respectively end, plan and side views of the packing strips. Figs. 13 and 14 are end and side elevations of the cutoff valve. Figs. 15 and 16 are end and side elevations of the abutment disk, with the abutment detached. Fig. 17 is a cross section of the piston on lines 67 of Fig. 18. Fig. 18 is a side elevation of the piston.

To the base plate W are attached the pillow blocks K and H, which are constructed respectively with the journal boxes K and H having the journal caps K and H In these journals is mounted the shaft N, to which is secured the cylinder disk 0 concentric with it. The rotating cylinder is constructed of the said disk and the inner ring 0' and the outer ring 0 respectively and the disk 0 securely bolted together; between these rings and disks is formed the annular cavity into which the steam is admitted, acting against the rotating cylinder.

and the inner wings A the abutment I and the pistons A and B. The inner rings 0 are provided with packing rings (1 which pack against the flanges D of the abutment disk hereinafter described. Said rings are provided with flanges O at the piston seats which complete the circles of the rings, allowing complete ring packing to be used. The disk 0 and outer ring 0 of rotating cylinder are provided respectively with ribs (3 and G which brace and strengthen The cylinder is also provided with the removable heads 0 which are constructed so as to have journal boxes A and B to receive the piston shafts A and A and B and B as shown in Fig. 1.

.Describing the piston A and its co-operating parts:Tl1e head 0 which receives the shaft A of the piston has the cap 0 which prevents loss of steam'through the journal. The piston shaft A is provided with the crank disk A which has the wrist pin A and the counterbalance A and is also constructed so asto receive the packing disk A which is adjusted by means of set screws A against the head 0 which receives the journal shaft A of saidpiston; suitable packing is placed between said packing disk and said head and prevents leakage of steam around said shaft. The piston shaft A is provided with nut A which holds crank disk A in place, and allows ready removal of same. The piston is mounted on the shaft A and A and is constructed of disks A and the outer wing A The disk'sAarepro vided with packingrings d The-pistohw'ving A is provided with cavity A and packing strips d packing against abutment D and its flanges D The edges A are s'lightlyangled so that their action on the packing'strips in pushing them into place when they protrude too far, is that of a shear. The piston disks A are also provided with openings A through which steam passes and balances them endwise.

The piston disk B, wings B and B shafts B and B, with their crank disk B counterbalance B, nut 13", and journals B and all parts are identical in construction and operation to piston disk A and all its co-operating parts.

The link is constructed of the arms E and bolt'E", and oscillates about said bolt.

E is in contact with cam 19 at 1).

E, placed on opposite sides of the cross central line 45, and connected 'to the hub E by flanged ribs E and E respectively as shown in Figs. 5 and 6. The arms E and E are provided with wearing strips E held in place by bolts E said arms are also connected bybolts E*, which pass through the outer end of arm E and the lug E at the outer end of arm E. The bolt E is securely attached to the rotating cylinder and forms the journal on which said link oscillates. Bolt E clears the hub and flanged ribs of the opposite link. The said link by its lug E is attached to the connecting rod 9 by the journal 6 the other end of the rod is connected to the Wrist pin A of the crank disk A by the journal 6; said connecting rod is made adjustable in length by the rightand left nuts 6 The said connecting rod transmits the motion given the link by the double cam, to the pistons, so that the pistons make their oscillations at the proper intervals as hereinafter described.

The link arms F, F and flanged arms F and F hub F wearing strips f bolts F and F journal bolt F and lug F and connecting rod f, with its journals f and f and right and left nuts f are identical in construction and operation to arms E, E and connecting rod e'and their co-operating parts, respectively.

The stationary double cam er and b is constructed so that the curve a? of cam a and curve I) of cam 6, form a truecam, the same is true of curve a of came a and curve 19 of cam I). These curves a and 0. b and b may be eccentric tangential curves to the inner curves a and b intersecting the outer curves a and-b respectively. The curves a 19 a and b are concentric to the center of revolution of the rotating cylinder. The curves a a, 19 andb and a b and a, b produce respectively periods of rest and throw in the operation of the links; said cam is attached by bolts G to cam disk G, which is firml y se cured to the pillow block H, by-lug G; said cam has alsothe hole G through which the rotary shaft N passes, but. is not necessarily in contact with it.

- Referring to Figs. 1, 2, 5 to 8 inclusive, the link is attached to thecylinder by journal The arm E' isin contact with cam a at a and arm Revolving the link with the rotary cylinder, arm E is thrown by the curve I) of cam 1), curve- 01, of

cam on allowing E to follow. Arm E passes to "curve 19 of cam I) and arm E to curve a of cam a and is held stationary during substantially half the revolution. The armE comes in contact with a, of cam a, andis thrown, and'curve b of cam 11 allows arm E to follow it. Arm E passes to curve a of cam a and ring to Fig. 7, particularly, it will be seen that the period of rest a and b, is much shorter than the periods of rest a and b during said long period of rest which is substantially half the stroke, the steam is acting on the pistons, and during the short period, the pistons are passing the abutment. As before stated the curve a of cam a,and curve I) of cam 12, form a true cam, the same is true of curve a of cam a and curve 19 of cam b.

As will be seen in Figs. 1, 2 and 6, the link is constructed so that the arm E travels on cam 01, and arm E on cam 12. The curves of the throw and rest of the cams are so constructed that while the link takes the motion imparted to it by the double cam, no loose play is allowed between the link and the said cam; the links are reversed in position and appear to interlock,-but in reality clear each other; that is, the arm Eofonelink and the correspondingarm F-of the other,are-on op posite sidesof the cam a, the same-is true of arms E and F being on opposite sides of cam b. The cams aand b are'provided with wearing strips a and b respectively.

The packing strips P in the piston seats are constructed with the cavity 15, in which is placed the springp said strips are beveled as shown at 10 to allow them to be pushed back into place by the piston wings should they protrude too far. Thekeys p whichfit in grooves 19 prevent the packing strips from protruding too far. Said packing-stripsat their ends are provided with cavity 19 which gives play to packing rings d of the piston disks-A and B and allows themto pack against the piston seats without interference. openings 19 are located so that the steam maypass through and balance the strips under steam'pressure. Packings P, except the cavityp are identical in construction'to packings P above described. Packings' P are constructed with a cavityp at one end only.

,formed byuinner rings 0 of the rotating cylinder, is the abutment disk D, D ,-provided with the flanges D*,on which is mounted abutment I, provided with packing strips P; said disk may be made in parts or-integral as shown, and bolted to the abutment stand D by bolts D, said stand D, as shown, may be made integral with the pillow block K, bythe Web K and the ribs K and 'K if desired; however, it may be made separate. The abutment disk contains the steam and exhaust portsX and g respectively. The-steam chest X is located in said abutment disk and connects with the steam'port by the passages X and X Within said steam chest X is the oscillating valve z, provided with the central port Z and formed of'the lips z z, and flanges 2 provided with the cavity'z for the reception of the rocker shaft B; said valve controls the introduction of thesteaminto the cylinder. The exhaust port 74 is connected to the exhaust y by passage 1 the steam and exhaust pass through the passages 00' and The 40 tionary double cams are so arranged that the y, which connect with theirrespective ports. The steam enters at pipe as, and exhausts at pipe y, as indicated by the arrows. Said abutment disk is also provided with the bolt holes D to receive the bolts D which attach it to pillow block K. The hub of the abutment disk is provided with packing rings (1', which pack against the inner periphery of the inner ring of the rotating cylinder, (and prevents the leakage of any steam that may have escaped past packing rings 01;) said disk has also'the hole N, through which the shaftN passes, but said shaft is not necessarily in contact with it.

The cut-off valve Z is operated by the rocker shaft R, which is mounted in journal boxes R. The lever formed by the hand bar S and the hub S is secured to the rocker shaft R, and is connected to the crank disk S, by the end S of the connecting bar S which is connected to the lever formed by the bar S and hub S, by journal pin S it is evident that the crank disk S, operating as an eccentric, controls the cut-off.

M represents the driving pulley on shaft N.

In locomotives or other engines requiring it, crank disk S may be dispensed with and suitable cut off devices provided, and the shaft N extended as shown, on both sides of the pillow blocks.

The operation is as follows:The steam enters through pipe X, and is controlled by the cut-0E in its introduction into the cylinder. It is confined between the abutment I, and the pistons A and B, respectively, during the revolutions of the engine. The oscillations of the pistons pass abutment Z, are controlled by the links E and F, through the connecting rods e and f, and the crank disks A and B The periods of rest and throw in the staoscillations of the pistons occur when they are balanced, 'i. (2., when under exhaust, or when steam pressure surrounds them. The pistons are stationary, with regard to the cylinder, during substantially half of their respective strokes when they are under steam pressure, and are propelling and rotating with the cylinder. The pistons after passing port 11 allow the steam to escape through the exhaust pipe Y. The operation of the steam in the cylinder is similar to that in engines shown in letters above mentioned.

I do not limit myself to the constructions shown, as the same may be varied without departing from the spirit of my invention.
